Referring to the drawing, the numeral 1 0 designates generally a downspout which is adapted to discharge into a soil pipe II. The soil pipe His formed at the upper end thereof with an enlarged coupling sleeve 12terminating at the upper end thereof in an annular flange ll.

A strainer structure generally designated as I4 is suspendingly mountedin the upper end of the soil pipe H, and comprises a cylindrical body I5which is formed with a perforated bottom wall v6.

The upper portion of the body I5 is formed with an annular flange 11adapted to seat on the shoulder l8 formed by the enlarged couplingmember I2. A cylindrical upwardly projecting flange I9 projects from thehorizontal flange l1, and an upper annular flange 20 extends outwardlyfrom the upper end of the cylindrical flange IS. The upper flange 20 isadapted to substantially seat on the flange l3 of the soil pipe ll.

As shown in Figure 2, the down spout i0 terminates at a point slightlyabove the upper end of the soil pipe H, and in order that the water orother liquids will drain into the soil pipe II, I have provided acylindrical sleeve 2| which is secured by fastening means 22 to thelower end of the down spout l 0. The sleeve 21 telescopes over the lowerend of the down spout l0 and terminates at a point axially within theupper portion of the soil pipe H.

An inverted cup-shaped member 23 is disposed loosely about the sleeve 2|and comprises a top wall 24 having a cylindrical side wall 25 looselyengaging within the cylindrical flange 19. The lower end of the sidewall 25 is adapted to rest on the annular flange IT. The cup-shapedmember 23 provides a means for concentrically holding the sleeve 2.!with respect to the coupling member 12 of the soil pipe II.

Referring now to Figure 4, there is disclosed a soil pipe 26 which iscut off at the upper end thereof and is disposed substantiallyconcentrically beneath a down spout 21. A strainer generally designatedas 28 is suspendingly carried by the upper end of the soil pipe 26 andcomprises. a cylindrical side wall 29 formed with a plurality ofopenings 30, and a bottom wall 3| formed with a plurality of openings32. An annular flange 33 of variable width is carried by the upper endof the cylindrical body 29 and engages over the upper cut all end of thesoil pipe 26.

A sleeve 34 telescopes over the lower end of the down spout :21, beingsecured thereto by a set screw 35, and the sleeve 34 extends: downwardly into the upper end of the strainer 28. An inverted cup-shapedmember 35 is mounted on the upperend of the strainer 28 and comprises atop wall 31 having a cylindrical side :wall 38 engaging within the sidewall 29.. An annular flange 38 extends from the top wall 87 and is 34shown in Figure 4 will be used with the strain- In Figure 6 there isdisclosed another modification of this invention which is similar to theform shown in Figure 2. The strainer 42 is formed with a cylindricalintermediate part d3 and with a perforate conical lower part at.
